/**
 * The flag object is a design pattern similar to the media object, however it
 * utilises `display: table[-cell];` to give us control over the vertical
 * alignments of the text and image.
 *
 * http://csswizardry.com/2013/05/the-flag-object/
 *
 * 1. Allows us to control vertical alignments.
 * 2. Force the object to be the full width of its parent. Combined with [1],
 *    this makes the object behave in a quasi-`display: block;` manner.
 * 3. Reset inherited `border-spacing` declarations.

     * 1. Fixes problem with images disappearing.
     *
     *    The direct child selector '>' needs to remain in order for nested flag
     *    objects to not inherit their parent’s formatting. In case the image tag
     *    is wrapped into another tag, e.g. an anchor for linking reasons, it will
     *    disappear. In that case try wrapping the whole o-flag__img object into
     *    an anchor tag.
     *
     *    E.g.:
     *
     *      <a href="/">
     *        <div class="o-flag__img">
